Ultraslide...use at your own risk!

I was looking at the biggest loser store online and saw this little product for $300.  I had to laugh because I got one of these for Christmas about 15 years ago and it only cost about $50.  I wish I had saved it now but it's a pretty dangerous piece of equipment when you have balance issues.  Slicker than snot!
